I make these into a cloak clasp by adding it to another stamping and adding chains.
Here's the specification sizes for these wings . They are inches 2 1/2 (62mm) by 2 inches (50mm). They are raw brass and are ready for a patina or paint. They will oxidize over a period of time, but brush up to bright golden color if you use a steel wool (size 0000) pad on them.
